Measuring reaction times to number comparisons is thought to reveal a processing stage in
elementary numerical cognition linked to internal, imprecise representations of number …

How children's understanding of numerical magnitudes changes over the course of
development remains a key question in the study of numerical cognition. In an ongoing …

What representations underlie the ability to think and reason about number? Whereas
certain numerical concepts, such as the real numbers, are only ever represented by a subset …

The combined efforts of many fields are advancing our understanding of how number is
represented. Researchers studying numerical reasoning in adult humans, developing …

How do our mental representations of number change over development? The dominant
view holds that children (and adults) possess multiple representations of number, and that …

Nonsymbolic comparison tasks are commonly used to index the acuity of an individual's
Approximate Number System (ANS), a cognitive mechanism believed to be involved in the …

We investigated the relation between children's numerical-magnitude representations and
their memory for numbers. Results of three experiments indicated that the more linear …

Humans share with other animals a system for thinking about numbers in an imprecise and
intuitive way. The approximate number system (ANS) that underlies this thinking is present …

Numerical and mathematical skills are critical predictors of academic success. The last three
decades have seen a substantial growth in our understanding of how the human mind and …
